Every war has events where the tide changes, turning points where the conflict's endgame comes into focus.

That moment for the Second World War's European theater was June 6, 1944, the day Allied forces crossed the English Channel and began to reclaim the European mainland.

Friday marks the 71st anniversary of the D-Day invasion.

Here are images that bring to life one of the most consequential military operations in modern history.

It was overcast and foggy on June 6, 1944, when 160,000 troops landed on this French coastline.

Beaches along a 50-mile stretch of coastline in Normandy were given five names — Utah, Omaha, Gold, Juno, and Sword. German troops heavily defended each of them.

Cloud cover prevented Allied bombers from accurately targeting the German forces and softening up their defenses.

The market for mergers and acquisitions (M&A) is red hot right now. And the analysts at Goldman Sachs believe it could get hotter.

"Global M&A volumes are on pace to hit $4 trillion in 2015, just shy of the previous record set in 2007," Goldman's Robert Boroujerdi said. "However, M&A as a percentage of the world’s market cap sits at 5.8%, below the 20 year average of 6.7%. We would need to see a further $650 bn of announcements to close the gap."

Boroujerdi and his team have constructed a basket of 197 stocks that Goldman's clients can trade as a portfolio.

We pulled out the 12 stocks in the portfolio that have market caps above $5 billion and that Goldman believes have a "high, or 30-50%, probability of M&A activity in the next 12 months."

Management Outlook: In the Q1 earnings report, President and CEO Dan Dinges said while shale extraction is still efficient for the company, low oil prices are having some impact. "While pricing pressure remains a challenge for Marcellus gas in the near-term, Cabot's operating efficiencies in the play continue to exceed expectations," he said.

Your friends' Instagram feeds of selfies, brunch, and baby photos get tedious fast — unless those selfies happen to be taken with a whale or they brunch while hanging from a cliff face.

Luckily there are tons of amazing Instagram feeds from explorers and adventurers — many who have embarked on incredible journeys, set records for achieving things no person has done before, and advanced science by exploring the fascinating details of life on our planet — will add a dose of adrenaline and wonder to your day.

And in some cases, they might inspire you to drop what you're doing and go see the world.

In April 2015, Victoria's Secret announced its newest lineup of "angels."

These 10 women would be the faces — and bodies — of the iconic lingerie company.

One of these women is Elsa Hosk, a gorgeous 26-year-old Swedish model who has been making a name for herself for the past few years as one of the faces of Victoria's Secret's younger brand, PINK. But now, she's in a whole new class.

Not every model ascends to this level of recognition, but Elsa did — and we're only going to be seeing more of her in the years to come. 

Elsa is a pro now, but every supermodel has to start out somewhere. She has said she first started visiting modeling agencies when she was 13 years old — so her career has been more than a decade in the making.

But she had another passion: basketball.

She balanced modeling with basketball, which was no easy feat. "I played on a professional level until I was 17," she told Ground Mag. "Combined with school and modeling, it was a lot of work — but I loved it."

Flying with Virgin Atlantic is always an experience.

And for their customers traveling in and out of Los Angeles International Airport, the airline recently launched a brand new clubhouse that will coddle and relax. 

“We’ve always been focused on offering services that are conducive to the lifestyle in Los Angeles, from being the first airline to offer limo service to launching the concepts of onboard bars and seat-back entertainment,” Virgin Atlantic North America senior vice president Chris Rossi said in a statement. 

According to Virgin Atlantic, the clubhouse is set up to evoke the beauty of Southern California, to which the British airline recently celebrated 25 years of service.

Located in Terminal 2, the new Virgin Atlantic lounge is part of a $4-million investment to improve passengers' pre-flight experiences.

With more than 4,000 square feet of space, the lounge offers fliers a spacious and comfortable place to unwind before or after a flight.

Former Texas Gov. Rick Perry (R) became the latest notable GOP candidate to throw his hat into the presidential contest on Thursday.

He is far from alone. 

The GOP's 2016 field for the White House appears likely to be one of the most robust in modern history. There could be as many as 15 current and former senators, governors, and major business leaders in the race by this summer. 

However, there's not enough room for all of them.

This is especially true on the early debate stages that could provide a crucial opportunity for long-shots to shine. The two first debates, held in August and September, opted to impose strict guidelines to participate: The candidates must average in the top 10 in the national polls of the Republican race. (The two debates have varying procedures and calculate the poll average slightly differently.)

These guidelines leave some candidates much better positioned than others to catch fire on national television, though there's still time for even the stragglers to potentially surge into the to top 10 and make the debates.

On Friday afternoon, Business Insider collected the latest polling averages from Real Clear Politics to rank where the candidates would roughly stand if the debates were held today. We also gave our take as to some of their political liabilities and assets as they seek the Republican nomination.

#1 — Former Florida Gov. Jeb Bush (R)

Bush is expected to announce his candidacy June 15. His RPC polling average stands at 13.2%.

Strengths: Boosted by his family ties to former Presidents George W. Bush and George H.W. Bush, Jeb Bush has turned his super PAC into a fundraising machine. Additionally, Bush has a some of the top talent in the GOP behind him and his more moderate tone on social issues helps him with the party's elite.

Weaknesses: He has struggled to criticize the controversial mistakes made by his brother, George W. Bush, while in the White House. Jeb Bush could also be haunted by his relatively moderate policy positions on immigration and Common Core standards, two hot-button issues among conservative activists.

#2 — Wisconsin Gov. Scott Walker (R)

Walker says he'll announce his decision on the race later this summer. His RCP polling average is 12.5%.

Strengths: Walker earned love from national conservatives after he aggressively confronted his state's public sector unions. He then survived a tough recall fight and reelection battle as national unions unsuccessfully tried twice to oust him from office. Walker appears to be popular among both the GOP's establishment and its grassroots supporters.

Weaknesses: He's not a polished speaker and his off-the-cuff remarks have landed him in hot water several times. And he could be dogged by his flip-flop on immigration.

#3 — Sen. Marco Rubio (R-Florida)

Rubio launched his campaign in April and holds a 12% RCP poll average.

Strengths: Rubio is a relatively young, dynamic speaker and some Republicans predict his Cuban heritage could help the party reach out to Latino voters. Additionally, Rubio has carved out a hawkish foreign policy profile and has wealthy financial backers.

Weaknesses: Rubio's record includes a major flip-flop on his own immigration bill. Furthermore, some critics have compared him unfavorably to President Barack Obama, who also ran for the White House with just one Senate term under his belt. 

When the Women's World Cup begins on June 6, a whole bunch of players are going to become household names in their countries.

We went through all 24 World Cup teams and picked out one player from each team who's going to be incredibly important to her country's chances.

CANADA: Christine Sinclair (Group A)

Age: 31

Position: Forward

Thing to know: As the undisputed star for the host nation, Sinclair will hope to lead Canada to its first-ever Women's World Cup title. She's Canada's all-time goal scorer with 153 goals.

CHINA: Ma Jun (Group A)

Age: 26

Position: Midfielder

Thing to know: After missing the World Cup for the first time in their nation's history four years ago, China is hoping for a strong showing this summer. With forward Yang Li injured, China will now rely on Ma Jun, who leads the remaining group heading to Canada in goals scored with 15, and is one of its most experienced players.

NEW ZEALAND: Abby Erceg (Group A)

Age: 25

Position: Defender

Thing to know: New Zealand has failed to advance past group play in all three of its prior World Cup appearances, but will look to captain and star defender Abbey Erceg to help anchor their defense and break the trend this time around. Erceg certainly possesses the experience to do so, recently becoming the first New Zealand soccer player — male or female — to reach 100 caps.

Shopping may be dominated by online retailers like Amazon or up-and-comers like Warby Parker, but San Francisco's Westfield Mall is betting that some of these online companies might want to try the physical world, too. 

Business Insider attended the grand opening of Bespoke, a new co-working, events and demo space that's on the fourth floor of a mall that gets 20 million visitors a year.

While it may be in a retail center, it looks nothing like the stores surrounding it. What store has a bocce court and nap nooks?

Bespoke is in the middle of San Francisco's Westfield mall, next door to a Bloomingdales and below a Century Theatres.

The events side takes over the old location of a Borders Bookstore. How's that for the times?

The coworking space is designed so that online companies can come offline into the physical world, said Kevin McKenzie, global chief digital officer for Westfield.

Choosing to stay in someone's home instead of a traditional hotel is a simple way to spice up your vacation.

Vacation rental sites like Airbnb and HomeAway offer a plethora of interesting homes to choose from.

One of the best parts about traveling the world is getting to try different culinary specialties, and it seems like nearly every country has their own version of pizza. 

However, it might not be the typical tomato sauce, cheese, and bread combo you recognize.

From traditional Margarita pizza from Naples to a sweet and spicy banana curry pizza in Sweden, here are 21 types of pizza you can find around the world. 

Pizza is taken so seriously in Naples, Italy, that there is an organization called that Associazione Verace Pizza Napoletana that's devoted to upholding its authenticity. Rules specify that pizza should be no more than 2 millimeters thick and baked for 60-90 seconds in a a 485 °C stone oven with an oak-wood fire. Classic Neapolitan pies have a chewy crust and are usually topped with fresh artisanal ingredients, like tomato mozzarella, fresh basil, and garlic.

In Brazil, common pizza toppings include ham, cheese, corn, green peas, and hearts of palm.

In New Haven, Connecticut, pizza, or apizza, is cooked in an intensely hot brick oven to produce a more charred and crispy thin crust. These pizzas tend to include less cheese, and the “white clam pie” invented by Frank Pepe’s Pizzeria Napoletana, has become a staple with little neck clams smothered in olive oil, oregano, grated cheese, and chopped garlic.

1. Ralph Lauren

After studying business for two years at Baruch College in Manhattan, Lauren dropped out of school and joined the Army.

He left the Army in 1964, married Ricky Low-Beer and got a job at tie manufacturer A. Rivetz & Co.

Lauren made his mark going against the grain by designing wide ties in an era of skinny ties and started his own business, selling half a million dollars' worth of ties in the first year.

He's now a fashion tycoon worth $8.2 billion, with a global empire consisting of menswear, womenswear, jeans, fragrances, accessories and homewares.

2. Steve Madden

Madden attended the University of Miami for a short time but quickly landed back in his native New York in 1978 after his father stopped funding his education due to his fun-loving ways.

He gained experience working for a variety of footwear companies before starting his own in 1990 with just $1,100 in his bank account.

Madden has now amassed a fortune of $120 million and has expanded his footwear company into a lifestyle brand offering clothing and a number of accessories.

3. Bill Gates

One of the richest people in the world is a Harvard dropout.

Gates became interested in computer programming at age 13 and made his first $20,000 developing a computer program monitoring Seattle traffic patterns with Microsoft co-founder Paul Allen at age 15.

The two founded the multinational software company five years later.

He currently has a net worth of $86 billion.

With all of its healthy ingredients, Chipotle seems like it would be a smart choice for someone watching his or her waistline.

But the old adage "too much of a good thing" rings true here — oversized burritos stuffed to the max with rice, guac, meat, and more add up quickly.

Burrito-lovers don't have to worry about giving up Chipotle forever to avoid gaining weight though. Using Chipotle's nutritional data, we've broken down some popular Chipotle meals to show you where the calories are coming from — and how you can hack the menu to get the good stuff, without a day's worth of calories. 

There are 2,085 calories in a basic Chipotle meal!

Let's break down that burrito. Here's what's in a basic steak burrito with the works.

An obvious way to lighten up your burrito is to ditch the sour cream and cheese. Upgrading to brown rice, a slow burning complex carb, and chicken, with less fat and saturated fat than steak, makes the meal technically "healthier." But it doesn't save you too many calories — this burrito still has 1,080 calories.

Celebrities everywhere are showing off how high-tech they are by wearing the new Apple Watch in public.

Everyone from politicians to sports stars to singers and business executives have Apple Watches. But how much do they cost? We checked out the price of every famous figure's fancy new watch.

Russian Prime Minister Dmitry Medvedev was spotted wearing a space grey Apple Watch in a meeting with Putin. These are worth £339.

Saudi Arabia has been front and center over the past few months as oil prices plunged in late 2014 and then saw a mild recovery in 2015.

But it's worth taking a step back and looking at its unique economy as a whole and what that might mean for its future.

"The oil boom of the past decade has transformed Saudi Arabia into a major global economy with a young population and large wealth that offer great potential," writes HSBC economist Razan Nasser, "but with lower oil prices, the Kingdom's structural challenges are ever more pressing."

We've taken a closer look at some of the numbers behind Saudi Arabia young, oil-driven economy.

The Kingdom's Ghawar oil field has enough reserves to fill 4,770,897 Olympic swimming pools.

The Kingdom's oil reserves are huge.

Saudi Arabia's Ghawar field is the largest in the world. It has an estimated 75 billion barrels of oil left.

An Olympic-size swimming pool can hold 660,253.09 gallons of liquid.

Saudi Arabia's petroleum sector makes up 45% of GDP, which makes it bigger than the total GDPs of Iraq, Morocco, Rwanda, and Tonga combined.

Saudi Arabia's petroleum sector is 45% of the country's total GDP — which puts it at around $335,372 billion.

Iraq's GDP is $222.879 billion, Morocco's GDP is $104.4 billion, Rwanda's GDP is $7.451 billion, and Tonga's GDP is $466 million.

Saudi Arabia's population is slightly bigger than Texas's, but Texas's GDP is nearly 2 times as large.

Saudi Arabia's population around 28.8 million in 2013, which is slightly above to that of Texas' 26.5 million. However, Saudi Arabia's GDP in 2013 was around $750 billion, while Texas' was approximately twice that amount at $1.4 trillion.

Plus, Saudi Arabia has the 19th largest GDP — but if Texas were its own country, it would have the 13th largest GDP (just below Australia and right above Spain).

Overall, this suggests that Texas is more productive than Saudi Arabia.

Apple's mobile software has changed a lot since the first iPhone was unveiled in 2007.

Most people remember the polarizing flat design of iOS 7, but it can be tough to remember all the little changes that happened throughout the entire evolution of Apple's iPhone software.

From the first time Apple announced the App Store to the unveiling of Siri, here's how the iPhone's homescreen has changed through the years.

iPhone OS 1.0

Apple unveiled the original iPhone on January 9, 2007, and Steve Jobs said it was running a version of "OS X," the same software running on Apple's Mac computers. Apple later referred to its software as "iPhone OS" when it opened up the software to developers.

But there was no App Store on the original iPhone when it launched, and you couldn't download any third-party apps.

iPhone OS 2.0

Apple's second-generation iPhone, the iPhone 3G, shipped in July 2008 with iPhone OS 2.0 installed. Owners of the original iPhone could upgrade to iPhone OS 2.0, and it was worth it — this was when Apple introduced its App Store, and upgrading was the only way to gain access to the third-party apps that are partially responsible for turning the iPhone into a smash hit.

iPhone OS 3.0

Apple's iPhone OS 3.0 software launched in June 2009 and came pre-installed on the iPhone 3GS. The new software allowed iPhone owners to copy and paste text for the first time, and introduced the first landscape keyboard for messaging. Interestingly enough, many iPhone users today prefer texting while their phones remain in portrait mode.

Houses have been getting bigger and fancier for the last several decades, and we have the charts to prove it.

Every year, the Census Bureau releases data on the characteristics of newly constructed homes, and they recently released info on houses built in 2014.

We decided to take a look at how different aspects of new single family houses have changed over the last several decades.

The number of bedrooms has tended to go up. Nearly half of new houses in 2014 had four or more bedrooms.

Similarly, the number of bathrooms has increased. In 2014, 36% of new houses had three or more bathrooms.

Houses are getting taller. In 1973, two-thirds of new houses had one story. Since the late 90s, a majority have had at least two floors, and split-level homes have nearly vanished.

Most people will tell you they don't look forward to Sunday evenings.

In fact, a 2013 poll conducted by Monster.com found that a whopping 78% of surveyed adults worldwide experience the "Sunday night blues" on a regular basis.

Even if you love your job and typically look forward to getting back into the swing of things, "it's easy to feel a bit of trepidation on Sundays about the stresses waiting for you on Monday morning," writes Laura Vanderkam in her book "What The Most Successful People Do On The Weekend."

They spend quality time with their families, friends, and significant others.

Successful people know that their weeks will be jammed and that they are likely to be unavailable, says Roy Cohen, a career coach and author of "The Wall Street Professional's Survival Guide." So they make the most of their Sunday nights by spending time with their loved ones. 

They plan something fun.

"This idea may be the most important tip," Vanderkam writes. "This extends the weekend and keeps you focused on the fun to come, rather than on Monday morning." 

Vanderkam quotes Caitlin Andrews, a librarian, who says her extended family gets together for dinner almost every Sunday, alternating houses. "It takes my mind off any Sunday night blues that might be coming on," Andrews says.

You might also make Sunday a movie or spa night, or you could join a Sunday night bowling league.

They organize and plan for the week ahead.

Some successful people like to look at their calendars on Sunday night and set goals and deadlines for the upcoming week, says career coach Marsha Egan. The trick is to do this without stressing yourself out.

With the "Entourage" movie opening in theaters everywhere today, we're looking back on the 11 years since the show premiered in 2004.

Since the show ended its eight season run in 2011, the actors and actresses who made up the main cast have gone on to star in numerous television and movie roles — but none have managed to top their "Entourage" fame just yet.

See what Vinnie, Eric, Drama, Turtle, and Ari, the rest of the crew have been up to since the show ended.

THEN: Adrian Grenier played the young Hollywood movie star Vincent "Vinnie" Chase.

NOW: Grenier starred in the 2013 apocalyptic dramedy "Goodbye World" and became an environmental activist.

In March, Grenier's Kickstarter to fund a search for the "loneliest whale in the world" was saved at the last minute by a $50,000 donation from actor and fellow activist Leonardo DiCaprio.

Grenier and filmmaker Josh Zeman will use the proceeds from the fundraiser to film a team of scientists as they search for the lonely whale — called "52 Hertz" for the high frequency of its mating song that no other whale speaks.

THEN: Kevin Connolly starred in all 96 episodes of "Entourage" as Eric "E" Murphy.

It's been almost 10 years since Hurricane Katrina devastated New Orleans and other parts of the Gulf Coast. But the Crescent City, a cultural treasure that’s home to almost 400,000 people, faces even greater risks in the future.

Most of the city is already below sea level, protected by an unreliable system of levees.

Flood risk will grow more severe as rising sea levels and sinking coastal land produce a local increase of at least four feet by the end of the century. And then there's the inevitable increase in major storm surges caused by extreme weather events.

We've created a guide to the crises ahead and the city's best hope for survival.

More than 50% of New Orleans is already below sea level. The only things keeping the city safe are levees and flood walls.

But sea levels are projected to rise by around 4.5 feet this century as global warming causes water to expand and land ice to melt.

Sea levels are rising faster in Louisiana than almost anywhere else due to rapid sinking of marshy coastal land (orange shows land that disappeared between 1937 and 2000).
